Abstract
The invention relates to a lamp for motor vehicle headlamps, and in particular a high intensity discharge lamp, comprising at least one envelope which is arranged on a base and which is provided with two coatings arranged diametrically opposite one another, wherein the coatings (3) are identical in form and project at least 0.5 millimeters upwards beyond a horizontal plane in which, when the lamp is in the burnt-in position, the reference axis (R) which passes through the center of the base (4) lies.
Description
Technical field
The present invention relates to be used for the lamp of automotive headlight, and be particularly related to high-intensity discharge lamp, it comprises at least one shell, and shell is arranged on the pedestal (base), and provides two coatings that are oppositely arranged fully each other for shell.
Background technology
Use incandescent lamp as being used for the light source of automotive headlight for a long time at automotive field, and to increase the lamp that uses on ground just day by day be high-intensity discharge lamp, this is because high-intensity discharge lamp has presented sizable improvement at the light output facet with respect to incandescent lamp.In known discharge lamp, produce gas discharge between two electrodes in airtight discharge vessel, the light that this gas discharge emission is very bright.
For purpose of the present invention, for example having, the headlamp that is used for vehicle of dipped beam (low-beam) function is all headlamps that produce bright/dark dead line (cut-off), for example, the headlamp of a class as the distance light (high-beam) of pure lower beam headlamp and combination and lower beam headlamp.
Headlamp is equipped with usually launches the lamp of the visible light of color much at one on all directions in space, what this means then formation regularly is the path space that illuminates with even color (uniform color).For the automotive headlight strict requirement that had multiple standard and these norm-settings.So, for example the light of dipped beam (low-beam light) must have asymmetric light distribution, this asymmetric light distributes and has the bright/dark dead line of substantially horizontal clear qualification, thereby does not make approaching Pedestrians and vehicles (traffic) feel dizzy.For example, being used in the coordinate system on the Europe measurement screen, is 75R for the vital measurement point of headlamp scope, and the illumination of formulating for this measurement point is the minimum value of 12 luxs in the light time that headlamp switches to dipped beam.Bright/dark dead line only leaves described measurement point and extends half degree, and part (segment) III that is called covering appts (masking means) exceeds bright/dark dead line, and illumination can be not more than just in time 0.7 lux in part (segment) III of covering appts.Most of headlamps comprise so-called projection optics system and lens, projection optics system comprises ellipsoidal reflector, ellipsoidal reflector focuses on the light of light emitted on the covering appts that produces bright/dark dead line, and described lens produce so-called light and distribute in path space.Good headlamp is a feature to have contrast as well as possible in the zone of bright/dark dead line.
When just designing automotive headlight, more and more frequent an urgent demand is the light personalization that makes from the headlamp emission.When doing like this, light emitted shape must be in the standard of formulating, and, must guarantee that particularly reference color temperature is in ECE white (white field).
Summary of the invention
With respect to background technology, the purpose of this invention is to provide a kind of lamp that is used for automotive headlight, in the standard of formulating observing, this lamp makes it possible to launch personalized light beam.According to the present invention, this purpose realizes by following scheme: make identical in shape coating and coating is projected upwards and exceed at least 0.5 millimeter of horizontal plane, when lamp was in ageing state (burnt-in position), the reference axis by the pedestal center was arranged in described horizontal plane.
By means of the present invention, a kind of lamp that is used for automotive headlight is provided, this lamp makes it possible to launch personalized light beam when observing the standard of formulating.The identical shaped coating that is oppositely arranged fully each other makes that " painted " becomes possibility in the zone of bright/dark dead line, realizes desirable personalization thus.Coating is being a rectangle in shape preferably.
In one embodiment of the invention, the width of coating is 1.5 millimeters at least, and the length of coating is 2 millimeters at least.Can realize effectively dyeing in the zone of bright/dark dead line by this measure.
In an embodiment of the present invention, coating has two zones with different light transmissions at least, has realized that in this way color wherein has the dyeing of varying strength.Advantageously, zone has at least 40% light transmission.Preferably, zone has the light transmission less than 3%.
In one embodiment of the invention, setting has the zone of high light transmission, when making in being used in reflecting system or projection system, in the zone that the elbow of bright/dark dead line is twisted together (kink of elbow), by light generation maximal illumination by the coating transmission.In this way, in the standard of observe formulating, what can realize is noticeable design for light beam.
Preferably, the feasible only transmit blue of design coating.Blue light is distinguished for approaching Pedestrians and vehicles not being produced this fact of dizzy effect.
Description of drawings
Define other embodiments of the invention and improvement in other claims.Embodiments of the invention shown in the drawings will be described in detail below embodiments of the invention.
In the accompanying drawings:
Fig. 1 is the schematic diagram of the high-intensity discharge lamp watched from the side.
Fig. 2 is the profile along the line II-II among Fig. 1.
Embodiment
The high-intensity discharge lamp that has been chosen as embodiment comprises shell 1, is provided with burner (burner) 2 in shell 1, and shell 1 is connected with pedestal 4.
The position of installing with approximate horizontal in Fig. 1 shows high-intensity discharge lamp.In the case, extend by the center of pedestal 4 with the reference axis R shown in the chain-dotted line.Burner 2 sealing arc chambers 21, " salt lake " or halide pond 25 are positioned at the bottom of arc chamber 21.That seal and burner transmitted light 2 is made by quartz glass with vacuum-tight sealing.Arc chamber 21 is full of the ionized gas mixture, and the ionized gas mixture comprises at least a inert gas, particularly xenon, and the mixture of metal halide.Two electrodes that are connected with electric conductor 22,23 are arranged in the arc chamber 21 by common mode.Electric conductor 23 is connected to back bar (pole) 24 again, and the longitudinal axis that back bar 24 is roughly parallel to lamp advances to the pedestal 4 outside shell 1.Two gaps between electrodes have formed discharge path, and the center of arc chamber 21 also is positioned at the center of discharge path.
The coating 3 of two bar shape fully relatively is arranged on the surface of outside of shell 1 each other.In the present embodiment, each coating 3 all has three zones 31,32,33 with different light transmissions.In the present embodiment, the light transmission in zone 31 is 45%, and the light transmission in zone 32 is 25%, and the light transmission in zone 33 is 35%.Coating 3 is applied on the shell 1 symmetrically with respect to reference axis R.The width of coating 3 is chosen as the maximum gauge that is slightly less than arc chamber 21.
In the present embodiment, coating 3 adopts transmit blue and the form of the interference filter of reflect yellow.The center (center of the electric arc that promptly forms between electrode) that should center on light source by the length that makes coating 3 has at least two millimeters long to select the length of coating 3.What can realize in this way is effective " painted " in bright/dark dead line zone.
